To, all whom/it may concern.

a citizen ofthe United states," residing at.

.Hartford, in the county or- Hartford and Be it known that I, Amman 1R. HUNTEn,

other-source ofsupply to the molds of'twof or more shaping machines. For this purpose, one or more delivery troughs or conveyers are arranged to del ver the glass from, the sourceof supply to the moldsof the different machines, while the latter are at their receiving or charg ng statlons. .As.

is well understood in the glass Working art,

itis desirable to maintain substantial uniformity of outflow of the molten glass from the iurnace,-' whether fed constantly or intermittently, so as to preserve uniform heat conditions. It is sometimes necessary, how'- ever, to stop one ofthe shaping machines, for adjustment ,offits molds, or for other reasons In such cases it is desirable to 'continue the operation of the associated shaping machines, to Qavoid the loss of its production, and, forxthe reasons above glven,

it is also desirable'to continue the full and uniform feedl or flow of the molten [glass fromthe 'furnace. V 7

The present inventionis an apparatus for intercepting the charges of glass which wouldotherwise bedelivered to the sto ped machine gor machines, deflecting -them rom receptacle, without interfering withfthe delivery of the charges intended. forv the com their normal course .into a cullet pit or other panion machine or machines which are not stopped, thus enabling theother machine or machines to be continuedin operation.

This inventlon 1shere1n shown 111 conjunction with i a trough delivering apparatus.

which forms no part of the present invention, but is shown herein to illustrate the relation and -thegcooperation of thepresent invention therewith. l

Figure 1 of the accompanying drawings shows [a' s ide"elevationfwith the delivery trough conveyeror chute:1n section, of an apparatus for feedingicharges of molten,

glass to pressing orblowing molds and fordeflecting the charges according to. this invention from the molds of the stopped machine. Fig. 2 1s a plan view of the apparatus illustrated in Fig. 1, arranged for use 1 n connection with ,the molds of two forming machines, the delivery trough in this view being indicaed by dot-and-dash outline. Fig. 3 is a plan view of an apparatus which embodies this inventiondesi signed for use in connectionwith the molds of three glass forming machines. Fig. 4; is a side view of a deflector chute and its supporting means looking from the line 4-4 on Fig. 3. Fig. 5 is an end elevation of the deflecting chute in section taken on the line 5 5 of F i 3. Fig. 6 is adetail View showing one oi the chute moving handles and connections. y

The charges of glass are normally conveyed and delivered to y the machines by means of a delivering trough 1, which extends from beneath the outlet of the furnace or other glass container 7 toward the charging position or positions of the molds, far enough to insure delivery thereto. The troughs herein shown are inclined sufiiciently to allow the charges to slide along them by gravity, and-to acquire a momentum which will carry them across the inawn between the ends ofthe troughs into the respective molds in a path or trajectory indicated by the line .6 in Figs. 1 and 4, The troughs are, or may be, provided with suitable heat resisting linings 2, the surfaces of which may be lubricated with a stream or film of water. Near its upper end the trough is swiveled upon the end of a; swingingarm 3, which is pivotally mountedon astud 4, and is provided with a handle 5 by, means of which it may be turned so as to move the upper end of the trough into and out of position for receiving the gathersgfi as they are detached from the molten-glass container 7 or other source of supply.- The lower end of the delivery molds "it; o a reaati api is at aa other shaping machine, as these molds are successively brought into receiving or V the bed 32. Each of these chute blocks is V charging position. V

The harge del eri g aepafi u t us far described formsnopart of t 'e present invention, which relates -to "the intercepting and deflecting of the char es thus delivered,
